SD-9
a war droid produced on Balmorra for the Empire. It was built during the period of the reborn Emperor's reign on Byss. The original design of the war droid was done by Umak Leth and was basically a three-meter-tall, humanoid automaton armed with a plasma-burst cannon and a heavy repeating blaster, and protected by laser-reflective armor plating and an ionization shield system. Parts of the SD-9's programming and technology was borrowed from the Empire's Dark Trooper project, although this information was not initially released to the new Republic. Balmorran Arms failed to keep development costs down during the design of the SD-9, hoping to overcome the problems it had with earlier models. Thus, the SD-9 proved to be prohibitively expensive to anything smaller than a planetary government. Most SD-9s were conscripted by the Empire.
